What Is Blown-In Insulation?
Blown-in insulation is a loose-fill insulation material installed using specialized blowing equipment to improve thermal performance in attics, walls, and ceilings.
It helps reduce energy costs, improve indoor comfort, and increase overall home efficiency.
Why Proper Insulation Coverage Matters
- Improves home energy efficiency
- Reduces heating and cooling costs
- Enhances indoor comfort
- Helps meet building code requirements
- Prevents heat loss and air leakage
Recommended Attic Insulation Levels
| Climate Zone | Recommended R-Value |
|---|---|
| Warm Climates | R-30 to R-49 |
| Moderate Climates | R-38 to R-60 |
| Cold Climates | R-49 to R-60 |
